In this issue, we will discuss the recovery of platinum oxide, a process that is not overly complex. Generally, this process involves several key steps: collection, pretreatment, chemical treatment, and purification, all crucial in the realm of precious metals trading.

Before recovering platinum oxide, physical screening is conducted to select the platinum-containing portions for further processing. The platinum oxide is converted into a form that is easier for chemical treatment. The pretreatment process may include grinding and separation, where the parts with higher platinum oxide content are isolated from other materials, and sometimes thermal treatment is used to remove impurities.
Precious Metal Recycling
Next comes the critical stage of chemical treatment. The goal here is to reduce platinum oxide to metallic platinum. Strong reducing agents, such as hydrogen or other chemical reductants, are typically used to convert platinum oxide into metallic platinum.

After reduction, what we obtain is crude platinum, which then needs to be purified. Purification is carried out through methods such as electrolysis or chemical precipitation, aiming to remove impurities from the metallic platinum and enhance its purity. During electrolysis, crude platinum dissolves at the anode, while pure platinum deposits on the cathode, thus achieving purification.
